Juxta AC Watt Transducers

JUXTA AC WATT TRANSDUCERS1.GENERAL
The 2469 and 2489 AC Watt transducers produce an analog output equal to the Watts measured by the
input. The typical calibration is 500 Watts / element for 120V and 5A AC transformer secondary inputs.2.SPECIFICATIONS:Model #24692489Current input / range0-1 Amp AC or 0-5 Amp AC10 to 200% of rated input0-200% of rated inputCurrent input over range capability200% of rated input continuous
